的UIButton不能點擊的註解

Question

我遇到的問題對calloutView：我按一下按鈕，但似乎CalloutView收到代替的UIButton我點擊。

一些解釋第一：1。「SYSUMyAnnoCalloutView」是MKPinAnnotationView 2.「SYSUMyCalloutImageView」是一個UIImageView，我初始化它和addSubview對「SYSUMyAnnoCalloutView」 3. UIButton的和中的UILabel被addSubviewed了「 SYSUMyCalloutImageView」

相應的代碼： 1。在 「SYSUMyAnnoCalloutView.m」

- (void)setSelected:(BOOL)selected animated:(BOOL)animated 
{ 
if (selected){ 
    [self.calloutImageView setFrame:CGRectMake(-75, -100, 230, 130)]; 

    [self animateCalloutAppearance]; 
    //[self.calloutImageView becomeFirstResponder]; 
    //[self.calloutImageView.detailButton addTarget:self.calloutImageView action:@selector(clickForDetail) forControlEvents:UIControlEventTouchUpInside]; 
    [self addSubview:self.calloutImageView]; 
    [self setCanShowCallout:NO]; 
} 
else 
{ 
    //Remove your custom view... 
    [self.calloutImageView removeFromSuperview]; 
} 
} 

在 「SYSUMyCalloutImageView.m」

- (id)initWithImage:(UIImage *)image 
{ 
self = [super initWithImage:image]; 
if (self){ 
    //Label 
CGRect boundsForLabel; 
boundsForLabel.origin.x = 20; 
boundsForLabel.origin.y = 50; 
boundsForLabel.size.width = self.bounds.size.width - 100; 
boundsForLabel.size.height = 20; 
self.messageLabel = [[UILabel alloc] initWithFrame:boundsForLabel]; 
self.messageLabel.backgroundColor = [UIColor clearColor]; 
[self addSubview:self.messageLabel]; 
//detailButton 
CGRect buttonRect; 
buttonRect.origin.x = 20; 
buttonRect.origin.y = 80; 
buttonRect.size.width = boundsForLabel.size.width-50; 
buttonRect.size.height = 30; 
self.detailButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
[self.detailButton setFrame:buttonRect]; 
[self.detailButton setTitle:@"Click for detail" forState:UIControlStateNormal]; 
self.detailButton.userInteractionEnabled = YES; 
//[self.detailButton addTarget:self.superview action:@selector(clickForDetail) forControlEvents:UIControlEventTouchUpInside]; 
[self addSubview:self.detailButton]; 

} return self; }

有人可以解決我的問題嗎？將非常感謝:)

默認情況下，UIImageView不接受用戶交互。

你應該嘗試加入這一行的代碼在你的SYSUMyCalloutImageView.m

[self setUserInteractionEnabled:YES];
